The degradation of Reactive Red 6B (RR6B) wastewater was treated by Fenton oxidation using on-line spectrophotometric monitoring technology. The ratio of peroxide hydroxide concentration and ferrous ion dosage (HF) was investigated. Dyeing degradation process followed first order kinetics and Behnajady - Modirshahla-Ghanbery kinetics because of above 0.98 R2. Fenton process transient reaction rate and instant hydroxyl radical concentration was calculated. The optimum HF was 143 with 98% dye removal, 0.05mol/(L·s) instant transient reaction rate and 2.4×10-11mol/L initial hydroxyl radical concentration.

Abstract


The degradation of Reactive Red 6B (RR6B) wastewater was treated by Fenton oxidation using on-line spectrophotometric monitoring technology. The ratio of peroxide hydroxide concentration and ferrous ion dosage (HF) was investigated. Dyeing degradation process followed first order kinetics and Behnajady - Modirshahla-Ghanbery kinetics because of above 0.98 R2. Fenton process transient reaction rate and instant hydroxyl radical concentration was calculated. The optimum HF was 143 with 98% dye removal, 0.05mol/(L·s) instant transient reaction rate and 2.4×10-11mol/L initial hydroxyl radical concentration.
